    The VoIP Help Page Team·3 min read·Last updated: March 14, 2026

    This article provides a step-by-step guide on how to configure an Adtran Router/PBX to allow analog phones to register using user-based SIP credentials. It covers setting up trunks, individual analog user accounts, and dial permissions, then verifying registration status.

    Scope

    The following steps will allow you to use an Adtran Router/PBX to register analog phones using user-based SIP registration. You will create a trunk, create an analog user and configure SIP credential for each user, check the registration of the user status and finally create the dial permission for 3-4 digits extension to allow 3-4 digits calling.

    Requirements

    • Administrator privileges to the Adtran web console
    • SIP Phone Credentials
    • Tested on Adtran 924e, FW ver. R13.7.2.E
